Ochwo-Ssemakula, M., Sengooba, T., Hakiza, J. J., Adipala, E., Edema, R., Redinbaugh, M. G., Aritua, V., and Winter, S. 2012. Characterization and distribution of a Potyvirus associated with passion fruit woodiness disease in Uganda. Plant Dis. 96:659-665. This article describes the incidence and etiology of a viral disease of passion fruit in Uganda. Symptoms, including those characteristic of...

Flowers, as repeated modules on a plant, may show population dynamics that correspond to ecological models for population growth. We hypothesized that rate of flower production (birth rate), number of open flowers per day (population size) and flower duration (longevity) should be related to plant resource status. With dioecious species, resource demands of male or female function would contrib...

The sequential separation of male and female function in flowers of dichogamous species allows for the evolution of differing morphologies that maximize fitness through seed siring and seed set. We examined staminate- and pistillate-phase flowers of protandrous Saponaria officinalis for dimorphism in floral traits and their effects on pollinator attraction and seed set. Pistillate-phase flowers...

In hermaphroditic plants, female reproductive success often varies among different positions within an inflorescence. However, few studies have evaluated the relative importance of underlying causes such as pollen limitation, resource limitation or architectural effect, and few have compared male allocation. During a 2-year investigation, we found that female reproductive success of an acropeta...

Four studies investigated the impact of success and failure information on passionate individuals' performance. Obsessive passion, characterized by a rigid and defensive mode of functioning, predicted greater performance in domains both related and unrelated to the passionate activity in response to exposure to failure information. Conversely, harmonious passion, characterized by a flexible, no...

This study extends the existing satisfaction–trust–loyalty paradigm to investigate how customers’ affectionate ties with firms (customer–firm affection)—in particular, the components of intimacy and passion—affect customer loyalty in services. In a bilevel model, the authors consider customer–staff and customer–firm interactions in parallel. Through a netnography study and survey research in tw...

There may be many factors contributing to reduction in longevity and productivity in passion fruit plants, especially diseases of viral, bacterial or fungal etiologies, among which passion fruit woodiness, bacterial spot, root and collar rot, fusarium wilt, anthracnose and scab are the most important. The incidence of woody fruits in young plants totally compromises the productivity and quality...

There are times in your life where you entertain a passion and you want to find other people who share the same passion, are troubled by the same concerns, active in the same domain. They will understand your passion and will be glad to get into profound discussions on the finer points and angles of your shared issue of interest. Among one’s direct circle of acquaintances one can find a few fri...
